I had the same problem, but just copy all geometry from your SU file to another one and use V-ray.

The same problem occurs in my model sometimes. Copy and paste to new file help, but after some time a problem is back on.

I already made it, but it occurs again and again, I’ve tried to cleanup, purge all and divide the project. But I had to divide till the project get smaller.

This is an issue you should report on the Chaos Group forums.

Hi.
In my case, when I have this error it’s related to section planes. Everytime this error comes up I just delete all section planes and the render starts with no problem.

Hope it helps.
